Most portable chargers on the market are underpowered with low USB-C power output (18/30/45/60W). When charging devices that require a high USB-C output, like MacBook Pro (87W), it will take much longer than you wish or expect. SuperTank packs up to 100W of USB-C Power Delivery in a single port which can serve as both an input and an output. Thanks to its 100W output, SuperTank can charge your 15" MacBook Pro 2018 at full speed, only taking 1.5 hours to charge from 0% to 100% (when not in use). Together with 27,000 mAh capacity, SuperTank can even double your MacBook Pro battery life.

SuperTank can be charged at up to 100W via Power Delivery. To enable fast charging via Power Delivery, you need a wall charger that can deliver enough power (100W or more) as well as a USB-C cable that supports 5A current throughput.

The total maximum output of the four USB ports is 138W, putting SuperTank in a class of its own. Thanks to its two PD-enabled USB-C ports and two USB-A ports, SuperTank allows you to charge four devices at the same time, including laptops, tablets, cameras, cell phones, and other mobile devices. With USB-C Power Delivery becoming more and more popular, you can charge additional compatible devices such as security cameras, projectors, LED lights, and more.

With such powerful output, SuperTank can provide rapid charging for two laptops or tablets and two mobile devices all at once.

Pass-through charging is very helpful if you like to keep your portable charger at full capacity. With dual USB-C ports, you can charge SuperTank and your other USB-C compatible devices at the same time. 100W Power Delivery makes it possible to charge your laptop (up to 60W USB-C Power Delivery) when recharging SuperTank.

An ultra-high capacity portable charger does more than just charge your smartphone or tablet to full power multiple times. SuperTank’s massive 27,000 mAh capacity keeps you power on the go. It can extend your 15" Macbook Pro battery life for 8 hours or charge your iPhone XS seven times.

SuperTank is equipped with eight power cells, which are commonly used by premium electric vehicles but rarely seen in consumer electronics. Compared with traditional lithium-ion batteries, power cells provide 5x faster charging speeds and generate much less heat, reducing the risk of decreased performance or damage.

One thing worth special attention is SuperTank’s dual-temperature protection units (dual-NTC). This means even if one of the temperature protection units fails, the other back-up sensor will keep monitoring the temperature to ensure the safety of you and your devices.

SuperTank isn’t only designed for high-power devices. Most portable chargers on the market have a common problem: they are not able to charge low-power devices, as they have a minimum output ranging from 80mA to 150mA. However, some low-consumption devices, especially wearable devices, usually draw less current than that and cause a portable charger to automatically shut off.

X-Charge mode is designed to charge an almost unlimited range of low-power devices, including smart watches, Bluetooth earphones, fitness bands, and more. It's a great feature for people who enjoy exploring the outdoors or tracking their exercise.

Double-press the power button, and SuperTank will enter X-Charge mode and display the "X" icon. Double-press again to turn off X-Charge mode. With SuperTank, your wearable devices have never been treated better.

As a member of the Zendure A-Series battery family, SuperTank still adopts the classic ridged design. SuperTank is made from a durable composite material (polycarbonate + ABS) that's used in a vast array of other resilient products, including high-end suitcases. The exterior shell is reinforced by support ridges to resist warping. SuperTank is designed to be tough enough to go anywhere, while also making sure it looks good enough that you'd want to take it everywhere.

In the beginning, we have compared many form factors such as the long and slim shape that you often see the market from other products, but we decided to adopt this shape because of the following benefits:

1. The product is much shorter. Most 27,000mAh power banks on the market are really, really long, and it's actually taking a lot more space than the shorter form factor.

2. It can stand up firmly because of the design, so that a user can access the four ports conveniently.

3. The wider end surface enabled us to add four USB ports, instead of only three, and the digital LED screen in the middle, forming a perfect symmetry.

We worked tirelessly to produce a battery that functions perfectly and is easy to use.

SuperTank’s Digital LED Display lets you know exactly how much power is left so you won't get caught running on empty. This user-friendly feature is absolutely necessary for high-capacity portable phone chargers.

Sometimes, when you use a typical Power Delivery portable charger to power your laptop, it will charge itself instead. SuperTank comes with a PD direction switch feature to keep you in control. Give the power button a long press, and you’ll switch the direction of SuperTank’s power flow to ensure the laptop is being charged. Similarly, you could also allow the laptop to charge SuperTank by long-pressing the power button again.

With UPS mode, there will be no power interruption when switching between pass-through and battery mode, making it ideal for applications such as security system, microcontrollers, home automation, network storage, backup power for WiFi routers, and more. There’s no need to worry about short interruptions of power that will cause the devices being charged to reboot and lose data.
